0xCal weighs workout calories against budget

Hot take: don’t make this binary; default to conservative automation with explicit user control.

• –Automatically adding 100% of workout calories is usually too generous because wearable burn estimates are noisy.
• –A better default is to credit only part of the workout burn, with a clear toggle or slider for aggressive vs conservative tracking.
• –Users who are cutting weight probably want strict budgets by default; users maintaining or bulking are more likely to want earned-calorie flexibility.
• –Weekend overflow can be useful, but it should be transparent, capped, and easy to inspect so it does not turn into hidden drift.
• –The strongest UX pattern here is “smart by default, manual when needed,” not a fixed rule for every tracker.
